What is the selection process? Out of curiosity, does it matter when you send in an email application? Or do you wait until all of the e-mails are in and then select?

The selection process for smaller playtests like this one is based on numerous factors. We keep the application process open for a couple days (about 4-5 days) and collect all the information from the applicants. Once we close the application process, we go through and pick the playtesters based on factors like previous playtest reviews, interaction on the board, etc.
